Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive chloro and methoxy groups that allow for further functionalization. Its structure supports the development of compounds with selective activity against weeds and pests. Also employed in the preparation of pharmaceuticals where pyrimidine derivatives exhibit biological activity, including antimicrobial and antiviral properties. Commonly utilized in research and development for constructing complex heterocyclic systems in medicinal chemistry.
